See 7-12 . . . I think that should clear up any interpretation issues. The title of the section is Swing Center TRIPOD. The head does't move, but what is UNDERNEATH it may. And in 1-L #1 it says STATIONARY Post (player's head). The post is IMAGINARY . . . It ain't the spine. It is a line drawn up between the feets and up through the mellon. Also see Axis Tilt in the Glossary . . .

Mechanical - To change directions, the helicopter pilot alters the plane of the rotating blades by tilting their axis in the new direction.

Well put!!!

Golf - To change the plane of the Shoulder Turn without moving the Head, the golfer must tilt the Shoulder Axis by moving the Hips.

It all depends on your focus of the "staionary center". I think you can have a stationary head and that becomes a "head centered" pivot .... Colin Montgomery comes to mind. But if the head is to stay centered and I agree with Mr. Blake "set it there and keep it there", the multiple centers and hip shift "tilts" the axis to allow for this (in a dynamic motion).

Flexibility and conditioning and "too flat" of a shoulder turn have adverse effects on keeping this head centered IMO.
